Not exactly that way. If I remember correctly, it's one page per 1024 bytes in the
compressed file (so changing the compression level does change the number of pages), and then the pages are more or less evenly distributed by displayed characters (or maybe just characters, so comments and HTML code would count).
Ah, the relevant information is in the wiki:

Well, why not use a percent position? Beware of using the word "chapter", as not all books are split at chapter level, and even when they are the numbering could not match the actual chapter numbering, and that would be confusing.
